A. KING, OF WATERBURY, CONNECTICUT, ASSIGNOR TO SCOVILL MANUFAC- TUBINGCOMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CON- HINGED PINFASTENER.

Application filed January 3, 1928. Serial No 244,156.

The obj-ect of this invention is to provide a. snap-fastener element,either a socket or a stud, hingedly mounted upon a doublepointed pin andadapted to lock itself in position of use.

The invention consists of a snap-fastener member, either a socket or astud, hingedly mounted upon a double-pointed pin, so that it may beswung toward and from the limbs of the pin, said fastener member beingprovided below its hinging point with a prong which projects rearwardlybetween the limbs of the pin and serves to hold the device fromaccidental escape from the article to which it is applied, and said snapfastener member preferably being provided with pin-engaging means bywhich it is held `against the limbs of the pin, in closed position as Iwill proceed now more fully to explain and finally claim. y

In the accompanying drawings illustrating the invention, in the severalfigures of which i' like parts are similarly designated, Figure 1 is afront elevation; Fig. 2 is a rear elevation; Fig. 3 is a. longitudinalsection, and Fig. 4 is a transverse section on the line 4--4 of Fig. 1,illustrating one form of the invention. Fig. 5 is a front elevation;Fig. G is a rear elevation and Fig. 7 is a longitudinal section,illustrating another lform of the invention. Fig. 8 is a conventionalsectional view of a. portion of the back of an automobile seat with oneof the fasteners in position. Fig. 9 is a front elevation; Fig. 10 is arear elevation, and Fig. 11 is a longitudinal section, illustratinganother form of the invention. Fig. 12 is a front elevation; Fig. 13 isa rear elevation, and Fig. 14 is a longitudinal section, illustrating apreferred form of the invention. Fig. 15 is a fragmentary frontelevation illustrating the invention as applied to a stud member of a.snap fastener; Figs. 1 to 14 inclusive illustrating the invention asapplied to a socket member of a snap fastener.

1 may indicate the limbs of a doublepointed pin, having a transversehead 2, which in addition to connecting the limbs of the pin also servesas the pintle member of a hinge, the knuckle member 3 forming part of aplate 4 which is made or provided with a resilient socket 5, of knownconstruction, which is adapted to engage with a non-resilient or rigidlhead or stud of a snap fastener.

The end .of the plate opposite this knuckle member, 1s provided with aprong 6 extending rearwardly beyond the limbs of the pin the pin isapplied to hold the same in position and against accidentaldisplacement. Furthermore, the plate is provided with rearwardly turnedprojections 7 adjacent to the knuckle member and serving as means forkeeping the hinged member in position when it has been closed down onthe pin to its normal position, as shown in Figs. 1 to 7. Theseprojections 7 are more or less resilient, and snap into closed positionon the inside portions of the limbs of the pin next to its head.

Referring to Figs. 5 to 7, the pin head instead of being straight iselevated, as shown at 8, and this elevated part is of less width thanthe distance between the limbs 1 of the pin; there being shoulders 9provided at the junction of the upper portion of the limbs of the pinand the elevated portion 8 which serve to prevent the socket fromsinking into the upholstered material when it is mounted. Theprojections 7 on this construction cooperate with the sides of theextension .8. There are two bottom prongs 6 operating substantially asthe prongs 6 in the construction Shown in Figs. 1 to 4.

As shown in Fig. 8, the pin is inserted vertically in the-upholsteredarticle, and for this purpose the hinged member may be turned up intothe dotted lines position and then when the pin is driven home thehinged member lies on top of the upholstered member, in position to beengaged by the complemental 'fastener member on the .cover or otherarticle to be applied to the upholstered member.

As shown in Figs. 9 to 11, the limbs 10 of the pin are connected by across bar or head 11 to which the fastener member 12 is hinged, asbefore described, but just below the head, the limbs of the pin areconverged in angular relation, as indicated at 13, so that when the pinis inserted in an article, its limbs will yield, more or less, andthereby bunch the material of the article between the head and the bends13 where it is crowded and confined, and the thus crowded material isnot easily led through the narrow space between the bends 13 in theprocess of removing the pin from the material; and consequently thisconstruction of pin operates substantially .and adapted to engage thearticle to which l loo ` two parallel as a self-locking agency. The snapfastener member 12 is provided at its bottom with a prong 6, such asshown in Figs. 1 to 3 and operating in the same way.

In the preferred construction shown in Figs. 12 to 14, thedouble-pointed pin is the same as shown in Figs. 1 to 4 and its partsare similarly designated, but the snap-'fastener member 14, differs,excepting that it is shown with the socket element 5. Instead of asingle knuckle, it is provided with the pair of knuckles 15, and betweenthese knuckles there is the prong 16 extending rearwardly and upwardlyrelatively to the pin head, whereby the pin may be easily introduced inthe upholstery material when the hinged member is open. If the pin ismounted upon any kind of material in an open position, as indicated bythe dotted lines in Fig. 8, and the pin is pushed in as far as it willgo and the hinged member then closed, as indicated in Figs. 1 to 7 and 9to 15, into the normal position, which it Would occupy When mounted, theoffset prong 16 pierces the material, thus making it impossible toremove the pin while the hinged member is in closed position. The rongs17 at opposite sides of the hinged mem ier, are designed to create moreor less tension in connection with the parallel resilient limbs of thepin by their cooperation with the outer sides of the limbs to hold thehinged member in closed position, and. they also have a tendency toovercome lateral strains on the device. These prongs also enter theupholstery and serve to fix thefastener in position. In the cooperationof the prongs with the limbs of the pin, their action is in part andsubstantially the same as the projections 7 previously described.

The invention is especially applicable to attaching covers to theupholstered parts of automobiles, and when the pins are supplied withsocket members, the covers will be provided with the complementalsnap-fastener studs. may be supplied with hinged stud members 18, and insuch case the covers will have attached thereto the socket members. willbe stuck in the upholstery, points down, and in so doin-g the hingedmember' will be opened or raised, so as not to interfere with theinsertion of the pin up to its head, and thereafter the hinged memberwill be closed so as to thrust its prong or prongs into the upholstery.

By the provision of a hinged element, it is possible to stick the pinsin place vertically at right angles to the article, as indicated in Fig.8, thus ensuring facility of application. The hinged member will thenlie upon the outside of the article in convenient position to be engagedby its complemental member But, as indicated in Fig. 15, the pins Thepin on the article to be secured, such as a seat cover.

By the term snap-fastener member herein used, I mean to include thesnap-fastener element, whether a socket or a stud, and the plate onwhich it is made or to which it is applied.

`Variations in details of construction are permissible within theprinciple of the invention and the claims following.

l/Vhat I claim is i Y l. A snap-fastener member and a doublepointed pinhingedly connected, so that the snap-fastener member may be rotated onthe pin, and a prong on the snap-fastener member below and apart fromthe hinging eleon, the snap-fastener member having lateral projectionsextending rearwardly and cooperating with the limbs of the pin to holdthe snap-fastener member in closed position. 2 3. A snap-fastener memberand a doubley pointed pin hingedly connected, so that the snap-fastenermember may be' rotated on the pin and held against lateral movementthereon, the snap-fastener member having a rearwardly extended prong atoneend and projections from its opposite sides which are in tension withlthe limbs of the pin.

4. A snap-fastener member and a doublepointed pin hingedly connected, sothat the snap-fastener membermay be rotated on the pin and held againstlateral movement thereon, a prong extending rearwardly and upwardly fromone end of the snap-fastener member, and parallel rearward extensions onopposite sides of the snap-fastener member in resilient engagement withthelimbs of the pm.

5. A snap-fastener member anda doublepointed pin hingedly connected, sothat the snap-fastener member may be rotated on the pin and held againstlateral movement thereon, a prong extending rearwardly and upwardly fromone end ofthe snap-fastener member, and also having parallelvrearwardlyextending prongs in resilient engagement with the limbs of the pin andarranged on opposite sides of the snap-fastener member' below its hinge.
